Answer:
x27 + y.
Step-by-step explanation:
Binomial means having 2 terms so binomial of degree 27 is x^27 + y type.
For example,
x^27+y+2
If there are 2 degree terms of x, degree of the one having highest degree is taken.
For example,
In x^27+x^10
As highest degree is 27, this is a binomial of degree 27.
